La presente solicitud reivindica la prioridad de la Solicitud de Patente Provisional de Estados Unidos N° 62/555.875 presentada el 8 de septiembre de 2017.The present application claims the priority of United States Provisional Patent Application No. 62/555,875 filed on September 8, 2017.
Antecedentes de la invenciónBackground of the invention
La presente invención se refiere en general a la mezcla de fluidos y, más particularmente, a dispositivos mezcladores estáticos o inmóviles para la mezcla de fluidos y a un método para fabricar la unidad mezcladora estática.The present invention relates generally to the mixing of fluids and, more particularly, to static or immobile mixing devices for mixing fluids and to a method of manufacturing the static mixing unit.
Los dispositivos mezcladores estáticos se utilizan ampliamente en diversas aplicaciones para producir la mezcla o fluidización de mezclas de múltiples componentes, así como para facilitar la reacción química, la transferencia de calor y/o la transferencia de masa de corrientes de fluidos. Una serie de dispositivos mezcladores estáticos generalmente se colocan de extremo a extremo dentro de una tubería u otro conducto a través del cual fluyen las mezclas de múltiples componentes o las corrientes de fluido, con dispositivos mezcladores estáticos adyacentes girados entre sí en un ángulo preseleccionado alrededor de un eje longitudinal del conducto.Static mixing devices are widely used in various applications to produce mixing or fluidization of multi-component mixtures, as well as to facilitate chemical reaction, heat transfer and/or mass transfer of fluid streams. A series of static mixing devices are typically placed end-to-end within a pipe or other conduit through which multicomponent mixtures or fluid streams flow, with adjacent static mixing devices rotated relative to each other at a preselected angle about a longitudinal axis of the duct.
Un tipo popular de dispositivo mezclador estático utiliza dos o más rejillas de elementos cruzados a modo de hoja que están dispuestas para cruzarse entre sí en un ángulo preseleccionado y también para estar situadas en ángulo con respecto al eje longitudinal del conducto. Los elementos cruzados en cada rejilla están separados una distancia correspondiente a la anchura de los elementos cruzados de la rejilla de intersección, de manera que los elementos cruzados de las rejillas de intersección se intercalan y están en contacto lateral entre sí en los puntos de cruce. Estos elementos cruzados en contacto son típicamente elementos individuales que deben ser mantenidos en su lugar y después deben ser soldados en los puntos de cruce para asegurarlos juntos.A popular type of static mixing device uses two or more grids of leaf-like cross elements that are arranged to intersect each other at a preselected angle and also to be situated at an angle to the longitudinal axis of the duct. The cross elements in each grid are separated by a distance corresponding to the width of the cross elements of the intersecting grid, such that the cross elements of the intersecting grids are sandwiched and are in lateral contact with each other at the crossing points. These contacting cross members are typically individual members that must be held in place and then welded at the crossing points to secure them together.
La construcción de las rejillas de intersección de los dispositivos mezcladores estáticos mediante la soldadura de los elementos cruzados de contacto individuales es un proceso que requiere mucho tiempo y mano de obra. Además, en aplicaciones, tales como la mezcla de polímeros, donde el dispositivo mezclador estático está sujeto a caídas de presión elevadas, estas soldaduras en los bordes laterales de los elementos cruzados están sometidas a tensiones elevadas que, con el tiempo, pueden provocar el fallo de las soldaduras. La Patente de Estados Unidos N° 5.435.061 describe un enfoque para simplificar el proceso de construcción mediante la utilización de un proceso de fundición de metal para formar partes o subconjuntos del dispositivo mezclador estático. A continuación, los subconjuntos se unen para formar el dispositivo mezclador estático. Si bien el número de soldaduras requeridas para construir el dispositivo mezclador estático se reduce en este proceso, sigue existiendo la necesidad de un proceso de construcción de dispositivos mezcladores estáticos que aumente la resistencia de los dispositivos mezcladores estáticos al reducir el número de soldaduras, pero que tampoco requiera la fundición de subconjuntos.Constructing the intersecting grids of static mixing devices by welding the individual contact cross elements is a time- and labor-intensive process. Additionally, in applications, such as polymer mixing, where the static mixing device is subject to high pressure drops, these welds on the side edges of the cross members are subjected to high stresses which, over time, can lead to failure. of the welds. United States Patent No. 5,435,061 describes an approach to simplify the construction process by utilizing a metal casting process to form parts or subassemblies of the static mixing device. The sub-assemblies are then joined together to form the static mixing device. While the number of welds required to construct the static mixing device is reduced in this process, there remains a need for a static mixing device construction process that increases the strength of the static mixing devices by reducing the number of welds, but that nor does it require the casting of subassemblies.

Descripción detalladaDetailed description
Volviendo ahora a los dibujos con mayor detalle e inicialmente a las Figs. 1 a 3, una realización de un dispositivo mezclador estático está designada generalmente con el número 10 y se muestra dentro de un conducto cilíndrico 12 a través del cual se pretende que las corrientes de fluido fluyan y se mezclen a medida que pasan a través del dispositivo mezclador estático 10. El dispositivo mezclador estático 10 ocupa una sección transversal del conducto 10. Aunque solo se ilustra un único dispositivo mezclador estático 10, normalmente se colocan múltiples dispositivos mezcladores estáticos 10 en una relación de extremo a extremo dentro del conducto 12, con los dispositivos mezcladores estáticos adyacentes 10 girados unos con respecto a otros alrededor de un eje central longitudinal del conducto 12.Turning now to the drawings in greater detail and initially to Figs. 1 to 3, one embodiment of a static mixing device is generally designated 10 and is shown within a cylindrical conduit 12 through which fluid streams are intended to flow and mix as they pass through the device. static mixer 10. The static mixer device 10 occupies a cross section of the duct 10. Although only a single static mixer device 10 is illustrated, multiple static mixer devices 10 are typically placed in an end-to-end relationship within the duct 12, with the Adjacent static mixing devices 10 rotated relative to each other about a central longitudinal axis of the duct 12.
El dispositivo mezclador estático 10 comprende rejillas de intersección 14 y 16 compuestas de elementos cruzados en forma de hojas deflectoras separadas y paralelas 18 y 20, respectivamente. Las rejillas 14 y 16 y las hojas deflectoras individuales 18 y 20 se cruzan entre sí en un ángulo incluido que puede estar en una realización dentro del rango de 45 a 135 grados y en otra realización puede estar dentro del rango de 60 a 120 grados. Las rejillas 14 y 16 y las hojas deflectoras 18 y 20 también están situadas formando un ángulo, que normalmente es la mitad del ángulo incluido, con respecto al eje central longitudinal del conducto 12.The static mixing device 10 comprises intersecting grids 14 and 16 composed of crossed elements in the form of separate and parallel deflector sheets 18 and 20, respectively. The louvers 14 and 16 and the individual deflector sheets 18 and 20 intersect each other at an included angle which may be in one embodiment within the range of 45 to 135 degrees and in another embodiment may be within the range of 60 to 120 degrees. The grilles 14 and 16 and the deflector sheets 18 and 20 are also located at an angle, which is usually half the included angle, with respect to the longitudinal central axis of the duct 12.
Las hojas deflectoras 18 en cada una de las rejillas 14 están intercaladas y cruzadas con las hojas deflectoras 16 en cada una de las rejillas de intersección 16 asociadas. Las hojas deflectoras 18 y 20 pueden tener forma de tiras rectangulares, excepto las hojas deflectoras 18 y 20 que están situadas más cerca de la superficie interior del conducto 12 que tienen una forma que se adapta a la forma de la superficie interior del conducto 12. Las hojas deflectoras 18 son planas y las hojas deflectoras 20 tienen dos segmentos planos 20a y 20b que están s en planos desplazados por una parte doblada 20c. Los planos desplazados pueden ser paralelos entre sí.Deflector sheets 18 in each of the grids 14 are interspersed and crossed with deflector sheets 16 in each of the associated intersecting grids 16. The deflector sheets 18 and 20 may be in the form of rectangular strips, except the deflector sheets 18 and 20 which are located closer to the inner surface of the duct 12 which have a shape that conforms to the shape of the inner surface of the duct 12. The deflector sheets 18 are flat and the deflector sheets 20 have two flat segments 20a and 20b that are in planes offset by a folded portion 20c. The displaced planes can be parallel to each other.
Las hojas deflectoras 18 dentro de cada rejilla 14 tienen extremos opuestos 22 y 24 y bordes laterales opuestos 26 y 28. Las hojas deflectoras 20 dentro de cada rejilla 16 también tienen extremos opuestos 30 y 32 y bordes laterales opuestos 34 y 36. Los bordes laterales 26, 28 y 34, 36 de las hojas deflectoras 18 y 20, respectivamente, incluyen partes sin cortar que unen las hojas deflectoras intercaladas 18 y 20 adyacentes a lo largo de una tira transversal 38 donde las hojas deflectoras 18 y 20 se cruzan entre sí. Esta tira transversal 38 crea una fuerte conexión integral entre las hojas deflectoras adyacentes 18 y 20 que se extiende por toda la anchura de cada rejilla 14 y 16 y elimina la necesidad de situar y después soldar o unir las hojas deflectoras individuales 18 y 20. Los bordes laterales 26, 28 y 34, 36 incluyen partes cortadas que se extienden desde las partes sin cortar hasta los extremos opuestos 22, 24 y 30, 32 de las hojas deflectoras 18 y 20, respectivamente.The deflector sheets 18 within each grille 14 have opposite ends 22 and 24 and opposite side edges 26 and 28. The deflector sheets 20 within each grille 16 also have opposite ends 30 and 32 and opposite side edges 34 and 36. The side edges 26, 28 and 34, 36 of the deflector sheets 18 and 20, respectively, include uncut portions that join the adjacent interleaved deflector sheets 18 and 20 along a transverse strip 38 where the deflector sheets 18 and 20 intersect each other . This transverse strip 38 creates a strong integral connection between the adjacent deflector sheets 18 and 20 that extends the entire width of each grille 14 and 16 and eliminates the need to position and then weld or join the individual deflector sheets 18 and 20. Side edges 26, 28 and 34, 36 include cut portions extending from the uncut portions to opposite ends 22, 24 and 30, 32 of the deflector sheets 18 and 20, respectively.
La parte doblada 20c que coloca los segmentos 20a, 20b de la hoja deflectora 20 en los planos desplazados puede tener la forma de un pliegue en forma de S 40 que incorpora la tira transversal 38. Como se puede ver en la Fig. 3, el pliegue en forma de S 40 acorta la longitud longitudinal de las hojas deflectoras 20 en relación con la longitud longitudinal de las hojas deflectoras 18, creando así aberturas en forma de hendidura 42 entre los extremos 30, 32 de las hojas deflectoras adyacentes 18 en la proyección axial de la superficie sólida del dispositivo mezclador estático 10. Se cree que estas aberturas 42 y el pliegue en forma de S 40 en las hojas deflectoras 20 facilitan la mezcla de las corrientes de fluido cuando fluyen a través del dispositivo mezclador estático 10.The folded portion 20c that positions the segments 20a, 20b of the deflector sheet 20 in the offset planes may be in the form of an S-shaped fold 40 incorporating the transverse strip 38. As can be seen in Fig. 3, the S-shaped fold 40 shortens the longitudinal length of the deflector sheets 20 relative to the longitudinal length of the deflector sheets 18, thereby creating slit-shaped openings 42 between the ends 30, 32 of the adjacent deflector sheets 18 in the projection axial of the solid surface of the static mixing device 10. These openings 42 and the S-shaped fold 40 in the deflector sheets 20 are believed to facilitate the mixing of fluid streams as they flow through the static mixing device 10.
En cada par de rejillas de intersección 14 y 16, el extremo 24 de cada una de las hojas deflectoras 18 no está cortado y está unido a un extremo 22 igualmente sin cortar de una de las hojas deflectoras 18 en otro de los pares de rejillas de intersección 14 y 16 a lo largo de un pliegue inverso 44 que alinea uno de los pares de rejillas de intersección 14 y 16 con otro de los pares de rejillas de intersección 14 y 16 para formar un subconjunto de dispositivo mezclador estático 46 como se muestra en las Figs. 4 y 5. En otra realización, el extremo 24 de solo algunas de las hojas deflectoras 18 no está cortado y está unido a un extremo igualmente sin cortar 22 de una de las hojas deflectoras 18 en otro de los pares de rejillas de intersección 14 y 16 a lo largo del pliegue inverso 44 para formar el subconjunto de dispositivo mezclador estático 46. In each pair of intersecting grilles 14 and 16, the end 24 of each of the deflector sheets 18 is uncut and is attached to an equally uncut end 22 of one of the deflector sheets 18 in another of the pairs of intersecting grilles 14 and 16. intersection 14 and 16 along a reverse fold 44 that aligns one of the pairs of intersecting grids 14 and 16 with another of the pairs of intersecting grids 14 and 16 to form a static mixing device subassembly 46 as shown in Figs. 4 and 5. In another embodiment, the end 24 of only some of the deflector sheets 18 is uncut and is attached to an equally uncut end 22 of one of the deflector sheets 18 in another of the pairs of intersecting grilles 14 and 16 along the reverse fold 44 to form the static mixing device subassembly 46.
Los extremos sin cortar interconectados 24 y 22 de las hojas deflectoras 18 crean una fuerte conexión integral que elimina la necesidad de posicionar y después soldar los extremos 24 y 22 de las hojas deflectoras individuales 18. Cada hoja deflectora 18 se muestra con un extremo cortado 22 o 24. En otra realización, el extremo cortado 22 o 24 está reemplazado por un extremo sin cortar 22 o 24 que después se conecta a un extremo sin cortar 22 o 24 de las hojas deflectoras 18 en otro de los pares de rejillas de intersección 14 y 16 a lo largo de otro de los pliegues inversos 44, de modo que tres de los pares de rejillas de intersección 14 y 16 estén alineados entre sí. De esta manera se pueden unir pares adicionales de rejillas de intersección 14 y 16.The interconnected uncut ends 24 and 22 of the deflector sheets 18 create a strong integral connection that eliminates the need to position and then weld the ends 24 and 22 of the individual deflector sheets 18. Each deflector sheet 18 is shown with a cut end 22 or 24. In another embodiment, the cut end 22 or 24 is replaced by an uncut end 22 or 24 which is then connected to an uncut end 22 or 24 of the deflector sheets 18 on another of the pairs of intersecting grilles 14 and 16 along another of the reverse folds 44, so that three of the pairs of intersecting grids 14 and 16 are aligned with each other. Additional pairs of intersecting grids 14 and 16 can be joined in this way.
En una realización del subconjunto de dispositivo mezclador estático 46, el extremo 32 de cada hoja deflectora 20 en la rejilla 16 está separado del extremo 30 de la hoja deflectora 20 alineada longitudinalmente en la rejilla adyacente 16 para crear un espacio 48. Como se ilustra En la Fig. 6, el espacio 48 se puede dimensionar para recibir al menos parte del pliegue inverso 44 en los extremos sin cortar 22, 24 de las hojas deflectoras 18 en otro de los subconjuntos del dispositivo mezclador estático 46 para que los extremos 32, 30 de las hojas deflectoras 20 se puedan soldar o fijar de otro modo a los extremos sin cortar 22, 24 de las hojas deflectoras 18 para unir los dos subconjuntos de dispositivo mezclador estático 46 entre sí. Los subconjuntos de dispositivo mezclador estático adicionales 46 se pueden unir de esta manera.In one embodiment of the static mixing device subassembly 46, the end 32 of each deflector sheet 20 in the grate 16 is spaced from the end 30 of the longitudinally aligned deflector sheet 20 in the adjacent grate 16 to create a gap 48. As illustrated in Fig. 6, the space 48 can be sized to receive at least part of the reverse fold 44 at the uncut ends 22, 24 of the deflector sheets 18 in another of the subassemblies of the static mixing device 46 so that the ends 32, 30 of the deflector sheets 20 can be welded or otherwise attached to the uncut ends 22, 24 of the deflector sheets 18 to join the two static mixing device subassemblies 46 together. Additional static mixing device subassemblies 46 may be joined in this manner.
En algunas realizaciones, como se muestra en la Fig. 7, algunas o todas las hojas deflectoras 18 y/o algunas o todas las hojas deflectoras 20 pueden incluir aberturas 50 que permiten que partes de las corrientes de fluido pasen a través de las hojas deflectoras 18 y/o o 20 para facilitar la mezcla de las corrientes de fluido.In some embodiments, as shown in Fig. 7, some or all of the deflector sheets 18 and/or some or all of the deflector sheets 20 may include openings 50 that allow portions of the fluid streams to pass through the deflector sheets. 18 and/or or 20 to facilitate mixing of the fluid streams.
Volviendo ahora a las Figs. 8 y 9, se ilustra una pieza de partida 52 en forma de lámina plana de un material, tal como un metal o una aleación, a partir de la cual se elabora uno de los subconjuntos de dispositivo mezclador estático 46. La pieza de partida 52 ha sido cortada para formar los extremos cortados 22, 24 y las partes cortadas de los lados 26, 28 de las hojas deflectoras 18, así como los extremos cortados 30, 32 y las partes cortadas de los lados 34, 36 de las hojas deflectoras 20. Los pliegues en forma de S 40 que se formarán en las hojas deflectoras 20 y los pliegues inversos 44 que se formarán entre los extremos 24 y 22 de las hojas deflectoras 18 adyacentes longitudinalmente se muestran con líneas discontinuas. Después de cortar la lámina plana de material para formar la pieza de partida 52, el subconjunto de dispositivo mezclador estático 46 se forma doblando la pieza de partida 52 en las ubicaciones de los pliegues en forma de S 40 y los pliegues inversos 44. Debido a que los lados adyacentes de las hojas deflectoras 18 y 20 están unidos integralmente en las partes no cortadas de sus lados 26, 28 y 34, 36 a lo largo de la tira transversal 38 y las hojas deflectoras 18 adyacentes longitudinalmente están unidas integralmente en sus extremos no cortados 22, 24 a lo largo del pliegue inverso 44, el subconjunto de dispositivo mezclador estático 46 está formado como un elemento de una sola pieza sin necesidad de soldar las hojas deflectoras separadas. Esto da como resultado un subconjunto de dispositivo mezclador estático 46 de alta resistencia que se puede fabricar más rápidamente y con menos coste de lo que sería necesario si las hojas deflectoras 18 y 20 tuvieran que soldarse entre sí. De manera similar, el dispositivo mezclador estático 10 se puede ensamblar rápidamente a partir de los subconjuntos de dispositivo mezclador estático 46 con un mínimo de soldadura requerida.Turning now to Figs. 8 and 9, a blank 52 is illustrated in the form of a flat sheet of a material, such as a metal or an alloy, from which one of the static mixing device subassemblies 46 is made. The blank 52 has been cut to form the cut ends 22, 24 and the cut parts of the sides 26, 28 of the deflector sheets 18, as well as the cut ends 30, 32 and the cut parts of the sides 34, 36 of the deflector sheets 20 The S-shaped folds 40 that will be formed in the deflector sheets 20 and the reverse folds 44 that will be formed between the ends 24 and 22 of the longitudinally adjacent deflector sheets 18 are shown with dashed lines. After cutting the flat sheet of material to form the blank 52, the static mixing device subassembly 46 is formed by folding the blank 52 at the locations of the S-shaped folds 40 and the reverse folds 44. Due to that the adjacent sides of the deflector sheets 18 and 20 are integrally joined at the uncut portions of their sides 26, 28 and 34, 36 along the transverse strip 38 and the longitudinally adjacent deflector sheets 18 are integrally joined at their ends not cut 22, 24 along the reverse fold 44, the static mixing device subassembly 46 is formed as a one-piece element without the need to weld the separate deflector sheets. This results in a high strength static mixing device subassembly 46 that can be manufactured more quickly and at less cost than would be necessary if the deflector sheets 18 and 20 were to be welded together. Similarly, the static mixing device 10 can be quickly assembled from the static mixing device subassemblies 46 with a minimum of welding required.
